Maybe so, I could be wrong. But my experience has been with RG142 which I had
a
bunch of at one time. In the AZ sunshine the jacket cracked and I had a mess
of
tarnished silver on my hands. And if you pigtail this stuff and try to seal
it,
nothing wants to stick.
(In my location where I run cable on the ground instead of digging trenches in
the desert that will show for 100 years, I have a choice of rattlesnakes or
pack
rats. I try to leave the snakes alone to keep the rats down, but when they
come
into the garage, they have to go and we have a rat problem. I tried cats, but
the coyotes and owls like them. So it's Heliax to the rescue.)

#### Both 142 and also 393 use the same FEP-9 outer jacket. I found only
one site that stated
FEP-9 could be used outdoors. All the other sites mention nothing about
outdoor use.
I have an application where some short lengths of 393 will have to be used
outdoors. I think
to be safe, I will wrap the entire length with some 33 or 88 tape first.
Then UV should not
be an issue. That or some of that split loom plastic stuff.
